Java Bridge Mode (Bridge Mode)Bridge definition: separates abstraction and behavior, and is independent of each other, but can be dynamically combined. Why is Bridge Mode usually used? When an abstract class or interface has multiple concrete

--Explore the design pattern seriesTERRYLEE,2006 year MayAbstract: The structural pattern, as the name implies, discusses the structure of classes and objects, which use inheritance to combine interfaces or implementations (class-structured patterns)

To sum up the precautions for the class: 1. do not perform too many logic-related initialization in the constructor; 2. the default constructor provided by the compiler does not initialize the variables. If other constructor is defined, the compiler

24th Chapter, Bridging mode Bridge mode, also known as bridge mode, is one of the structural design patterns. The bridge mode embodies the principle of single duty, the principle of opening and closing, the principle of replacing the

Constructors are not polymorphic, they are actually static methods, and the static is implicitly declared Objects have state, behavior, and identity. This means that each object can have internal data (which gives the state of the object) and
